| Abstract: | This paper makes a study of the influence of the high temperature jet environment around the missile on the missile during the launching of the missile launcher with a concentric vertical launching device.Through the design of the bottom part of the outside cylinder of the concentric system,the reflection of the high temperature jet can be reduced,thus decreasing the scorch of the high temperature jet point of the missile launching cylinder.The paper also makes use of the numerical value method to give a numerical simulation with the two measures.The result shows that the two measures bring a certain effect in improving the heat and pressure environment during the missile launching. |
